Conclusions
Spark-ignition engine - Control functions

The rapid development of digital control platforms adapted to the automotive engine environment has led to huge advances in vehicle performance. This improvement has been made possible :

• on the one hand, by the direct action of the control on the motor, due to the relevance of the algorithms and the adaptation of calibrations;

• secondly, by the presence of a high-performance control system that reduces behavioral dispersion and enables the engine designer to better optimize his technological choices.

The generalization of engine control has necessitated a major effort to harmonize the dynamics of two industrially very different worlds: the internal combustion engine and its physical peripherals have performances in the general sense of the term that are constantly improving, but at a slower rate than that of the components used in microcomputing....
